APPARATUS FOR SAWING WOOD.

SPECIFICATION forming part of Letters Patent No. 756,917, dated April12, 1904. Application filed January 16, 1904. Serial N0.189,285. (Nomodel.)

To all whont it may concern:

Be it known that I, WILLIAM R. WALKER, a citizen of the United States,residing at Fort Smith, in the county of Sebastian and State ofArkansas, have invented an Apparatus for Sawing Wood, of which thefollowing is a specification.

This invention is an improvement in sawingmachines, and relates moreespecially to the class of portable apparatus for sawing firewood intosuitable lengths.

- The primary object of the invention is to provide a saw-carrying frameor apparatus for the purpose of suspending a crosscut-saw at one end ofthe latter and in such manner that the said saw may be conveniently andeasily operated by a single person.

A further object of the invention is to so construct and arrange theparts of the sawcarrying frame as to assist the operation byautomatically returning the saw after each stroke.

Other objects of the invention are to provide an apparatus of thischaracter which shall be simple in construction, light and durable, maybe conveniently moved from place to place, and will greatly reduce thelabor usually required to operate a crosscut-saw such as used inconnection with my improved apparatus.

The following specification enters into a full description of theconstruction and operation of my invention, and what I claim as new, anddesire to secure by Letters Patent, is more specifically set forth inthe appended claims.

In the accompanying drawings, which form a part hereof, Figure 1 is aperspective view of an apparatus for sawing Wood constructed Fig. 2 is adetail view of the swinging bar to which the saw is directly connected.Fig. 3 is a longitudinal vertical sectional view through the forwardpart of the frame.

Similar letters of reference indicate similar parts in all the views ofthe drawings.

In carrying out my invention I employ a frame consisting of thebase-board A, to which are firmly secured two pairs of uprights a (t anda a, the uprights of each pa1r being connected at the1r upper ends by across-piece (1,

and rod a and in practice I prefer that the uprights a, whichare'located at one end of the board A, be a little shorter than thecompanion uprights a. Extending between these pairs of uprights, at theupper end thereof, are longitudinal strips a, forming the top of theframe and provided adjoining the uprights a with a cross-piece a Thisframe is adapted to support the saw in the manner hereinafter described,and in order that the same may also form a support for thelogs or othermaterial to be sawed strips a are disposed diagonally and secured to thebase-board A and uprights a, projecting at their upper ends a slightdistance beyond the latter and so as to provide a log-rest after themanner of the ordinary sawbuck and at this point the frame is braced bymeans of a cross-bar (0 as is usual.

B designates a bar which is pivoted near its upper end upon a cross baror bolt (0 supported between the uprights a of the frame, and to saidbar at a suitable distance below its pivot is connected the rear end ofthe saw C, which latter is the crosscut-saw, usually re-' quiringtwopersons to operate it, one at either end, being a longstraight bladewith the teeth at the lower edge thereof. Said saw extends from theswinging bar forward in the frame between the uprights a and above thecrossbar (6 thereof and at its forward end is provided with a handle 0,by which it is operated. For the purpose of attaching the saw to the barB the latter is slotted, as at 6, and the connecting-pin o is passedthrough a transverse aperture in said bar, several such apertures beingprovided, so that the radius of movement of the pivot end of the saw maybe varied. The swinging bar is held at the cenreturn the saw after eachstroke, as is obvious.

At the end of the base-board A opposite the sawbuck is a vertical postD, suitably I00 braced by the pieces cl, and in the upper part of thispost is a vertical series of apertures 6?, into any one of which issecured a rod 6, extending therefrom through the frame and attached atits forward end to the crossbar cf, the said rod passing through a slotIf in the lower end of the swinging bar B, and in operation the said barwill contact with the rod and limit the movement of the saw, and forwhich purpose the rod is adjustable upon the post by means of theaforesaid series of apertures d Secured to one of the uprights a at asuitable distance above the sawbuck is a short wooden peg or pin f, theupper edge of which is recessed and V-shaped. This peg or pin is for thepurpose of, supporting the saw while the operator is placing a log uponthe sawbuck.

and being shaped as shown will prevent the saw from being accidentallydisplaced. 1 The operation of the apparatus will be readily understood,for after placing a log on the sawbuck the saw is removed from itssupport fand grasped by the handle 0, being then reciprocated back andforth in the usual manner and the rear en wung by means of the bar B andguided by the rod 6, which latter not only limits the reciprocalmovement of the saw, but also prevents any lateral movement of the rearend thereof. It will be seen, therefore, that the saw is manipulated bya single operator in the manner usual with two operators. The spring Dwill assist in the operations of the saw; but in some instances I maydispense with the same.

Having thus described my invention, I claim 1. In an apparatus forsawing wood, the combination, of a frame, a bar pivoted therein to swinglongitudinally thereof and provided at its lower end with a slot, asaw-blade pivoted at one end in the bar above said slot, and a guide-rodvertically adjustable in the frame and passing through the slot in theswinging bar, substantially as shown.

2. In an apparatus for sawing wood, the combination, of a frame, a barpivoted therein to swing longitudinally thereof, and provided at itslower end with a longitudinal slot, a sawblade pivoted in the bar andprovided at its opposite end with a handle, a post at one end of theframe, and a rod adjustably attached to the post, extending therefromthrough the slot in the swinging bar and attached atits other end to theforward part of the frame.

3. In an apparatus for sawing wood, the combination, of a frame, a barpivoted therein to swing longitudinally thereof, said bar being providedat' its lower end with a longitudinal slot and at its upper endprojecting above its pivot, a spring connected to the upper end of thebar and to the frame, a saw-blade adjustably pivoted in a slot in thebar and at its other end provided with a handle, a rod verticallyadjustable in the frame and passing through the slot at the lower end ofthe bar, a pin on the supporting-frame for supporting the saw, and asawbuck forming part of said frame.

4. In an apparatus for sawing wood, thecombination, of a framecomprising a base-board I and two pairs of uprights connected at theirupper ends, a bar pivoted between one pair of uprights and having a slotnear itslower end, a

saw-blade pivoted ,at one end in said bar and extendingtherefrom throughthe frame between the other pair of uprights and provided with a handle,inclined pieces secured to the latter uprights to form a sawbuck, asupporting-pin for the saw secured above the sawbuck to one of theuprights thereof, a post at the end of the frame opposite the sawbuck,

and a rod secured to said post and sawbuck, and said rod passing throughthe slot in the lower end of the swinging bar to which the sawis.connected; together with a spring connected to the swinging bar,substantially as herein shown and described. 7

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM R. WALKER.
